We now detect at runtime which sync features to use, which allows us to remove a lot of the compile-time configuration options. There is still one option though, to disable KHR_fence_sync on some devices (which are more efficient without it). - added a backdoor to get the vendor's EGL strings the new logic is: - use always ANDROID_native_fence_sync if available - fallback to KHR_fence_sync if available and not disabled by the compile-time option - use KHR_wait_sync if available and either of the above is enabled Change-Id: I9c4b49d9ff1151faf902cc93bd53ea5f205aaabf
